Can anyone help me with ignition timing spec's for KJ engine's.
Question: 1 What is the static timing figure.
2 How maney degree's extra do'es the simm's C4 magneto advance cam add to the static figure.
Any help on this greatly appreciated.
Thanks Graeme.
ps. The KJ bottom end is going in Deluxe frame with Ricardo cylinders so I'm not sure how much lead to give it.
I think the KJ probibly has twice the advance the deluxe has even with the deluxe closed combustion chamber. I think the flame front in KJ combustion will travel much faster than deluxe.Thoughts Please.
